Well, it's been almost 2 months on Cymbalta and here is what I've found..
NEVER forget to take it.. I spent today putting my fist through the wall because of it. Zapping head pain, irritability, and crying spells were just the start of some of the horrible withdrawl symptoms I felt and that was only one day off it.
Mind you, I like the way I feel on it, but there is one side effect I can no longer deal with - constipation. This made me so I was unable to go to the bathroom for a week. I had to use laxatives to go, which recently wasn't helping much either. It takes my appetite away for the most part, which does help the dieting.. however, the constipation doesn't help the weight loss.. which I found made me more frustrated.
I was originally put on 30mg and then 60, a week later. I have found that I felt much better on the 30mg, actually better than ever, with less of the side effects. And, BTW tink_4_me, I was getting super tired in the afternoon as well, I don't think it's a coincidence. I believe it's because of the high dose. I'm not a doctor and I'm not claiming to know better than one, but honestly, I think my pdoc should have left me at 30mg since it was working so well for me. My pdoc is a bad example, I believe, because he seems to be too busy to answer questions when I call or see him [And I see him once a month and have only called him twice in the last 2].
Basically what I'm trying to say is, if you are put on this drug and are having great results at 30mg, stay at that for a little while, it may be all you need. Going higher might make things worse, they did for me. I have read many accounts on countless message boards of the horrors of coming off this drug, and I now believe it. Just be aware that the withdrawl from this is no better than most ADs out there. I read a couple of people's accounts where they say these withdrawl symptoms are worse than Effexors. This is just an FYI, as this is the first AD I've ever been on. I just want you to know the things the pdocs won't tell you, just as mine didn't.
If you want anymore info, you can ask here or PM me. I can only tell you my experience so far.
